As shown in other documentation,
I map drive letters to use with Jcopy via the "net use" command. Recently, one
of the computers on my network would no longer run the cmd file successfully. I
got error messages like these after each "net use" command:

"System error 1130 has occurred.
Not enough server storage is available to process this command."

3. Double-click IRPStackSize (or if this registry setting doesn't exist,
create it with type DWORD and ensure the case is correct).

4. Change the base to decimal, set the value to 15, and click OK.

5. Reboot the computer.

====================================================================

Just in case that does not solve the problem,
another post by a Microsoft MVP suggests that you may have to keep
increasing the value until you achieve success:

"The default is 15. The instructions say to start
at the current value (or the default if no current value), and increase by 3,
until reaching a maximum(supposedly 50). Don't give
up at 18, or 21, or whatever. There's no one solution, it's trial and error,
unfortunately. And each trial is different."

====================================================================

As a postscript, I reinstalled Windows XP early in
November 2005. I also switched to using Acronis True Image and Acronis Disk
Director.

When I tried to run Jcopy, I got the "server storage" message.
I first increased the value of IRPStackSize to 15, but that was not enough. I had to increase it to 20 to
successfully use my mapped network shares.

I recently got this "server storage" message while trying to map a drive to another PC on my network.
Based on this post, the solution is to increase the IRPStackSize on the target machine (where the drive
exists).
